Framework for phase transitions between the Maxwell and Gibbs constructions at finite temperature
Constantinos Constantinou, Mirco Guerrini, Tianqi Zhao +2
The characteristics of the hadron-to-quark first-order phase transition differ depending on whether charge neutrality is locally or globally fulfilled. In -equilibrated matter,…
Large and massive neutron stars: Implications for the sound speed in dense QCD
Christian Drischler, Sophia Han, Sanjay Reddy
The NASA telescope NICER has recently measured x-ray emissions from the heaviest of the precisely known two-solar mass neutron stars, PSR J0740+6620. Analysis of the data [Miller e…
Limiting masses and radii of neutron stars and their implications
Christian Drischler, Sophia Han, James M. Lattimer +3
We combine equation of state of dense matter up to twice nuclear saturation density () obtained using chiral effective field theory (EFT), and…
Constraining hadron-quark phase transition parameters within the quark-mean-field model using multimessenger observations of neutron stars
Zhiqiang Miao, Ang Li, Zhenyu Zhu +1
We extend the quark mean-field (QMF) model for nuclear matter and study the possible presence of quark matter inside the cores of neutron stars. A sharp first-order hadron-quark ph…
Signatures for quark matter from multi-messenger observations
Mark G. Alford, Sophia Han, Kai Schwenzer
We review the prospects for detecting quark matter in neutron star cores. We survey the proposed signatures and emphasize the importance of data from neutron star mergers, which pr…
Simultaneous Fitting of Neutron Star Structure and Cooling Data
Spencer Beloin, Sophia Han, Andrew W. Steiner +1
Using a model for the equation of state and composition of dense matter and the magnitude of singlet proton superconductivity and triplet neutron superfluidity, we perform the firs…
Tidal deformability with sharp phase transitions in (binary) neutron stars
Sophia Han, Andrew W. Steiner
The neutron star tidal deformability is a critical parameter which determines the pre-merger gravitational-wave signal in a neutron star merger. In this article, we show how neutro…
Constraining Superfluidity in Dense Matter from the Cooling of Isolated Neutron Stars
Spencer Beloin, Sophia Han, Andrew W. Steiner +1
We present a quantitative analysis of superfluidity and superconductivity in dense matter from observations of isolated neutron stars in the context of the minimal cooling model. O…
Neutron star mass limit at supports the existence of a CEP
D. Alvarez-Castillo, S. Benic, D. Blaschke +2
We point out that the very existence of a "horizontal branch" in the mass-radius characteristics for neutron stars indicates a strong first-order phase transition and thus supports…
The Constant-Sound-Speed parameterization for NJL models of quark matter in hybrid stars
Ignacio F. Ranea-Sandoval, Sophia Han, Milva G. Orsaria +3
The discovery of pulsars as heavy as 2 solar masses has led astrophysicists to rethink the core compositions of neutron stars, ruling out many models for the nuclear equations of s…
Characteristics of hybrid compact stars with a sharp hadron-quark interface
Mark G. Alford, Sophia Han
We describe two aspects of the physics of hybrid stars that have a sharp interface between a core of quark matter and a mantle of nuclear matter. Firstly, we analyze the mass-radiu…
Constraining and applying a generic high-density equation of state
Mark G. Alford, G. F. Burgio, Sophia Han +2
We discuss the "constant speed of sound" (CSS) parametrization of the equation of state of high-density matter and its application to the field correlator method (FCM) model of qua…
Strangelet dwarfs
Mark G. Alford, Sophia Han, Sanjay Reddy
If the surface tension of quark matter is low enough, quark matter is not self bound. At sufficiently low pressure and temperature, it will take the form of a crystal of positively…
